Problem 4: IV Tube II For this second IV drip problem, the unknown is the tube diameter. Assume a free surface in the IV bag, where Pgage = 0, located 1.78 m above the patient's arm. The patient's blood pressure is 120 over 80, so the pressure in the vein is Pgage = 80 mm Hg. The smooth plastic tube is 1.5 m long. For medical reasons, we need a flow of Q = 10 mL/min. Assume fluid properties equal to water at 30°C. Part A Classify the flow: □ laminar □ turbulent Part B If all head loss is in the smooth plastic tube, what size (inner diameter) is required? [mm]

![**Problem 4: IV Tube II**
For this second IV drip problem, the unknown is the tube diameter. Assume a free surface in the IV bag, where \( P_{\text{gauge}} = 0 \), located 1.78 m above the patient's arm. The patient's blood pressure is 120 over 80, so the pressure in the vein is \( P_{\text{gauge}} = 80 \) mm Hg. The smooth plastic tube is 1.5 m long. For medical reasons, we need a flow of \( Q = 10 \) mL/min. Assume fluid properties equal to water at 30°C.
**Part A**
Classify the flow:
- [ ] laminar
- [ ] turbulent
**Part B**
If all head loss is in the smooth plastic tube, what size (inner diameter) is required? [mm]
**Illustration Description:**
To the right of the text, there is a cartoon featuring two characters involved in an IV setup. One character is administering the IV while the other is the patient receiving it. This visual aids in contextualizing the IV drip issue described in the problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc837c159-281c-429a-9ec5-8a70fc5b4137%2F2c952127-135d-464e-9451-8dd11d09eeb9%2F10mno6a_processed.png&w=3840&q=75)
